Impatiens plant named ‘Imtrarestar’

ABSTRACT

A new  Impatiens  plant, characterized particularly as to novelty by a flat and strong outward spreading growth habit, freely branching with branches that tend to grow horizontally, resulting in a big and floriferous plant with large carmine flowers with a distinct white star pattern.

Latin name of the genus and species of the plant claimed: Impatienswalleriana.

Varietal denomination: ‘Imtrarestar’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new distinct cultivar of Impatiens,botanically known as Impatiens walleriana.

The new Impatiens is a product of a planned breeding program conductedin Enkhuizen, Netherlands. The new Impatiens cultivar has a flat andspreading growing type, is floriferous with large flowers with adistinct star pattern and has attractive dark foliage.

The present cultivar originated from a cross-pollination made in 2002,of a proprietary Impatiens selection identified as ‘T3108-2,’ notpatented, as the female, or seed parent, with a proprietary Impatiensselection identified as ‘T2463-1,’ not patented, as the male, or pollenparent.

The present cultivar has been repeatedly asexually reproduced bycuttings in Enkhuizen, Netherlands, in Angers, France, in Gilroy, USAover a two year period. The distinctive characters of this new Impatiensare stable and reproduced true to type in successive generations ofasexual reproduction. It takes 6 to 8 weeks to produce a finished plant,depending on the temperature.

This new Impatiens plant is an annual in most climatical zones in theUS, only in zones 9 and 10 its a perennial plant.

DESCRIPTION OF THE DRAWING

This new Impatiens plant is illustrated by the accompanying photographicdrawing which shows blooms, buds and foliage of the plant in full color,the color showing being as true as can be reasonably obtained byconventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctivecharacteristics of this new Impatiens. The data which defines thesecharacteristics were collected from asexual reproductions carried out inEnkhuizen, Netherlands. The plant history was taken on 20 week oldplants, blossomed under natural light in the field.

Color readings were taken in the office under ambient light. Colorreferences are primarily to The R.H.S. Color Chart of The RoyalHorticultural Society of London.

Plants of the new Impatiens differ primarily from the plants of thefemale parent selection in the followig characteristics:

Plants of the new Impatiens have large, carmine flowers with a distinctstar pattern and a trailing habit, whereas the plants of the female havemedium sized purple flowers with a slight star pattern.

Plants of the new Impatiens differ primarily from the male plantselection in the following characteristics:

Plants of the new Impatiens have a trailing plant habit and a carmineflower with a white star pattern, whereas the plants of the male have acompact, upright plant habit and a red flower with a white star pattern.

The family relationship between ‘Imtrarestar’ and ‘Imtrarose’ is: Thefemale parent line of ‘Imtrarestar’ is a cross of ‘T0404-1’ with line‘R2938.’ ‘R2938’ is (‘RBGE 19821569’×‘J475-2’ crossed with ‘M1007-1’)crossed with (‘RBGE 19821569’×‘G2171-1’ crossed with ‘RBGE19821569’×‘J475-2’). The male parent line of ‘Imtrarose’ is ‘RBGE19821569’×‘J475-2’ crossed with ‘M1007-1.’
